| Abstract: | The copolymerization of 4|vinyl pyridine(4|VP) with acrylamide(AM) has been realized by radical copolymerixation in solution using potassium persulfate as initiator.The effects of acetone/water and DMF/water solvent systems,comonomer concentration,polymerization temperature,polymerization time and initiator amount on the conversion of the polymerization and molecular weight were investigated in detail.The results showed that the mixed solvent DMF/water=1( V/V) is suitable for the copolymerization of 4|VP and AM.The composition of copolymer was determined by ultraviolet spectrophotometry and the structure of copolymer was characterized and verified by FTIR and 13 C|NMR.Finally,The monomer reactivity ratios of 4|VP and AM were obtained with Kelen|Tudos method, r - 4|VP =0^644, r AM =0 371. |
